Summary: Add code coverage support / create gcov replacement
Product: new-bugs
Version: trunk
Platform: All
OS/Version: All
Status: NEW
Severity: enhancement
Priority: P
Component: new bugs

Neither Clang nor LLVM have the ability to generate coverage code for gcov.
Nor is there any replacement for gcov.
This means that code coverage cannot be measured when using the llvm/clang
toolchain.
For me, this is serious enough that I cannot switch exclusively to clang, I
must continue to support gcc as well.
On Mac OS/iOS, that's a big problem. More and more Objective-C features
_require_ clang (ex: "@synthesize by default" and "declare ivars in class
extensions"), thus developers will be forced to choose between these nice new
features and being able to measure code coverage. That's unfortunate.
Note: I've also filed <rdar://problem/8107317>.
